I did interviews for a while (granted that's not the same if you're pitching a startup). Man I hated it. All the recommended questions came with no real goal or anything to look for that I thought told me anything about what this person can do for me.
I guess maybe Zume they're just looking for a "good" answer to maybe indicate you could answer those kinds of questions in a pitch or whatever and not look bad... but what does that tell anyone anyway?
I asked other interviewers why they asked what they asked and what they thought it told them.
Everyone was just some myopic thing where they had a story where they had some bad employee and they think they're bad because X or good because Y and ask a question that they think shows them X or Y ... but nothing seemed to indicate that they really learned anything.
